DTC P2227 [WL-C, WE-C (Thailand, General (L.H.D. R.H.D.) specs.)]

id0102b0840700

DTC P2227

BARO sensor circuit range/performance malfunction
DETECTION CONDITION
•  The PCM monitors the input signal from the barometric pressure sensor. If the difference between the barometric pressure input from the barometric pressure sensor and the boost pressure is more than 11 kPa {0.11 bar, 1.6 psi}, the PCM determines that there is a malfunction in the barometric pressure sensor.
Note
•  If DTCs P2227 and P0106 are recorded simultaneously, the PCM determines that there is a boost sensor and barometric pressure sensor characteristic malfunction.
POSSIBLE CAUSE
•  BARO sensor (integrated in PCM) malfunction
